What is the reason why the Civic cannot connect to Bluetooth?
2 Answers
Civic's inability to connect to Bluetooth may be due to incompatibility with mobile devices. Other possible reasons: It could also be that the phone's Bluetooth function does not support car Bluetooth or that the call audio is not selected, or there may still be compatibility issues with the Bluetooth device. Introduction to car Bluetooth: The Bluetooth technology in the car Bluetooth system is an extension of the Bluetooth technology in mobile phones, with the same transmission system. Car Bluetooth is simply an in-car wireless hands-free system designed and developed based on wireless Bluetooth technology. The function of car Bluetooth is to automatically identify mobile phones, allowing connection to the phone without the need for cables or phone holders. The owner can control the phone without touching it, even keeping both hands on the steering wheel, and can use voice commands to answer or make calls.
I've repaired many Civic cars, and the most common issue with Bluetooth not connecting is either a software bug or a faulty Bluetooth module. If the infotainment system hasn't been updated for a long time, accumulated vulnerabilities can cause Bluetooth pairing to fail. It's also common for phones to become incompatible after an upgrade. First, try deleting all paired devices and restarting the head unit. Sometimes, low battery voltage can affect the signal, so checking the battery's health is important. Software issues can often be resolved with a simple reset, but a faulty module will need replacement. Unstable Bluetooth affects music playback and navigation, so don't waste time trying to fix it yourself—head straight to the 4S shop for professional diagnostics to prevent the problem from worsening. Regularly updating the system can help prevent these minor issues.
